Recommendations for air conditioning manufacturers based on product lines: For residential and VRF (Variable Refrigerant Flow) systems, consider Gree, Midea, and Haier (the top three domestic brands); for terminal units and air purification, look at TICA; for high-end Japanese brands, consider Daikin or Mitsubishi Electric.
First, determine the cooling load and system type based on the property layout, then select the appropriate manufacturer.
I.
VRF and Residential Systems: Gree, Midea, Haier
Gree (Founded 1991): GMV6S top-discharge DC inverter VRF (40HP ultra-large capacity, 55°C high-temperature operation, vapor-injected compressor, 2% ultra-low load ratio, connects up to 80 indoor units)—ranked #1 globally in compressor sales (approx. 112 million units in 2025, 35.9% market share); the top choice for large residences and commercial projects. Midea (Founded 1968): Modular units (top-tier with >20% market share), “Ku Sheng Dian” (Energy-Saving) ducted units with APF 4.85 (advanced energy efficiency), V8 series VRF (for hotels/office buildings, 40–45kW range, key export product)—known for high cost-performance and large export volume. Haier (Founded 1984): AI VRF (30% energy savings, dual-chip smart control, certified for 20 years of reliable operation, stable in extreme weather from -35°C to 60°C, launched at the Refrigeration Expo), MRV 7S (R32 full DC inverter)—ideal for smart and weather-resilient applications.
II. Terminal Units & Purification: TICA
TICA: Holds the #1 market share (over 15%) in terminal units and ranks in the top tier for modular chillers. A specialist manufacturer of purification air conditioning (for hospitals, electronics plants, and cleanrooms) and terminal equipment (fan coil units, air handling units);
a preferred choice for engineering projects (domestic custom HVAC solutions like TICA’s “Fred” series are also viable alternatives).
III. High-End Japanese Brands: Daikin, Mitsubishi Electric, Hitachi
Daikin: Benchmark for VRF technology (high inverter efficiency); Mitsubishi Electric: High-end commercial applications (large-scale building HVAC); Hitachi: Centrifugal chillers and VRF systems.
Choose Japanese brands for high-end office buildings or super-high-rises when the budget allows (premium branding, stable operation).
IV. Five Key Factors for Selection
1. System Selection: Residential split/ducted systems (small units), VRF systems (large residences/offices), chillers (large public buildings), and terminal units (fan coil units)—the building scale dictates the system; 2. Cooling Capacity: Determine capacity (HP/BTU/kW) based on floor area (estimated at approx. 200–250 W/m²); 3. Energy Efficiency: APF (split systems ≥ 4.8) or IPLV (VRF systems)—consider electricity costs and subsidies; 4. Connection Specs: Maximum number of indoor units (e.g., 80 for Gree VRF) and piping length limits; 5. Installation: Installation quality (copper piping, insulation, drainage) determines service life—the saying goes, “30% equipment, 70% installation.”
V. Key Considerations for Overseas Buyers
First, certifications: Compliance with CE, AHRI, F-Gas (EU fluorinated gas regulations), and R32/R410A refrigerant standards. Second, voltage: 220V/380V and 50/60Hz (export electrical specifications). Third, OEM/ODM: High flexibility from manufacturers like Midea, Gree, and AUX (offering private-label services across diverse product categories). Fourth, spare parts: Availability of compressors (from top-3 global suppliers GMCC, Landa, and Highly) and mainboards. Fifth, payment terms: 30% deposit and 70% balance prior to shipment. Industry experts advise evaluating air conditioning equipment based on product lines and energy efficiency: consider Gree, Midea, and Haier for VRF/multi-split systems;
Tica for terminal purification units; and Japanese brands like Daikin and Mitsubishi for high-end segments.
Buyers should align their requirements regarding cooling capacity, energy efficiency metrics (APF/IPLV), and installation needs before negotiating prices.
